sorry to keep pestering, now I need to fix the temp display. In the racecapture app the temp shows correct, the LUA script sets raw C temp to "* 1.8 + 32"

in laptimer the temp is off the chart, I removed the lua fix and set temp to "* 1" and harries looks right, just a degree or two off of what torquepro/odb2 shows, but then racecapture temp display is too low.

also does laptimer display brake switch onto the overlay if it's available? I see it in racecapture now, but I dont get pressure data just a yes/no on the switch itself

* 1.8 + 32 is a Celsius to Fahrenheit conversion. LapTimer expects Celsius currently (like used in OBD II).Not sure this has been changed lately in ASL's firmware or if it has been wrong from the beginning.I add this to the list of fixes for v21.

Oh, I forgot. To get brake pressure for analysis, two steps are required:

You need to get this data from the bus. As this is no standard OBD value, a car-specific custom PID is required for OBD. Not sure RCP has some tweaks built in here. As an alternative, you can use a dedicated brake pedal sensor connected to one of RCP's analog ports.

The analyzing software need to support brake pressure display. As it is so complicated to make 1) work, LapTimer has not built in support for brake values currently. However, I plan to add this feature for v21 and will use negative longitudinal acceleration in case brake pressure is not available.

I think this is a problem with race capture not your softwsre, I'm using lua to convert canbus to odb so I can just set it to leave it in c and I will report the issue to rcp devs
